Invest in your relationship with the Quran. Recite it. Understand it. Implement it. It is the Book. A guidance (2:2). A clear proof (4:174). A remembrance of God (7:2). A reminder (12:104). A mercy (17:82). A cure (17:82). A light (4:174). Fair warning (20:113). Glad tidings (2:97). Promises of ease. Happiness. Comfort. It increases your faith (8:2). Protects you from committing sins. It is a companion (Ahmad 394). A witness (Muslim 223). An intercessor (Muslim 1757). It is blessed (38:29) and a great blessing. And the reward and benefit from the Quran, is far greater than the effort of our investment.
Indeed, those who recite the Book of Allah, and establish the prayer and give (in charity) secretly and openly from what We have provided for them, they hope for a trade that will never yield a loss. That He may repay them in full their rewards, and give them (even) more from His Grace. Verily He is Oft-Forgiving, Most Appreciative. (Fatir 35:30-31)
